Regain an original fractional numeric value that Excel has transformed to a date value

问题

I have an Excel workbook that contains numeric values and some of them have been transformed by Excel auto format feature into the date values. I do not know the original numeric values and neither do I have access to the .txt version of that file.

Is there a way to calculate the value from the date? For example, what value was substituted by Excel to get: 08.01.2014.

This is not related to applying VALUE function to the date of changing cell format to "General."

EDIT#1:

If the value '42248' has somehow gotten into A1, then in another cell enter:

=--TEXT(A1,"d.m")

to retrieve the 1.9
